What is the worst kind of debt to carry? Is it student loan debt, credit cards, a mortgage — or something else? Even the experts don’t always agree on which debts are “good debt” and which ones are “bad” so imagine how confusing it can be to consumers who are dealing with debt!

Student Loan Debt

Why student loan debt is the worst: The loans are often given to young people with no credit experience and no clue how they will pay them back. Balances are often high, and the jobs borrowers counted on to make payments may be non-existent. (Some borrowers never graduate, which means they have debt but no degree to increase their earning power.) Finally, unlike every other type of consumer debt, it is very difficult to discharge balances in bankruptcy.

And why it may not be: College graduates, on average, still earn significantly more over their lifetimes than those without a college degree. In that sense, student loan debt can be considered an investment that pays off in future earning power. In addition, students may be able to defer payments on their student loans during times of economic hardship (albeit, usually at a cost), which makes them more flexible than other types of loans. In addition, borrowers may be eligible for reduced payments and loan forgiveness under the Income-Based Repayment Program or other loan forgiveness programs.

Credit Card Debt

Why credit card debt is the worst: With interest rates hovering around 15% on average — and more than 20% for some borrowers — credit card debt is often the most expensive kind of debt consumers carry. And with the low minimum monthly payments that issuers offer, cardholders can find themselves in debt for decades if they aren’t careful.

And why it may not be: While making minimum payments on credit cards is not a great idea over the long run, having that option can come in handy in a financial pinch. It can give cardholders time to get back on their feet without ruining their credit.

And when consumers can’t pay back credit cards, they don’t have that much to lose — at least when compared to falling behind on a home or auto loan. Sure, a credit card issuer may be able to sue a cardholder to collect, but that usually happens only after months or years of not paying, and after there’s been an opportunity to work out some kind of settlement on the debt.

Mortgage Debt

Why mortgage debt is the worst: If you wonder how bad mortgage debt can be, just ask the owners of some 8.8 million homes that CoreLogic said had negative or near-negative equity as of the second quarter of 2013. That means those owners owe close to, or more than, what the property is worth.

That also means they can’t sell those houses without without shelling out money to pay off their mortgage or doing a short sale that damages their credit scores. Even for those who aren’t underwater, rising taxes and/or insurance premiums, the cost of maintenance, and loans that typically take 30 years to pay off can make one’s home feel like a financial prison at times.

And why it may not be: Over time, homeownership remains one of the key ways average Americans build wealth. If you are able to keep up with your home loan payments, eventually the home will be paid off and provide inexpensive housing or rental income. Equity that has built up can be accessed through a reverse mortgage or by selling the house, or it can be passed along to heirs — sometimes tax-free.

When it comes to credit scores, this type of loan will generally help, as long as payments are made on time. Even large mortgages shouldn’t depress credit scores, unless there are multiple mortgages with balances. That’s usually a problem that affects real estate investors, though; not homeowners with one or two homes.

Tax Debt

Why tax debt is the worst: If you owe the Internal Revenue Service or your state taxing authority for taxes you can’t pay, you can suffer a variety of painful consequences. If a tax lien is filed, your credit scores will likely plummet. In addition, these government agencies usually have strong collection powers, including the ability to seize money in bank accounts or other property, or to intercept future tax refunds.

And why it may not be: The IRS offers repayment options that may allow a tax debt to be paid off over time at a fairly low interest rate. (Similar programs are available for state tax debt in many states.) And unlike applying for a loan, you don’t have to have good credit to get approved for an installment agreement.

The good news when it comes to credit scores is that tax debt itself isn’t reported to credit reporting agencies; a tax lien is the only way that it may show up. By entering into an installment agreement, you may be able to get a tax lien removed from your credit reports, even before you’ve paid off what you owe.

Loans For Nearly Every Credit Level

Auto Loan Debt

Why auto debt is the worst: The average auto loan now lasts five and a half years, and some 12% last six to seven years, according to Edmunds.com. That means payments will last long after that new car smell has worn off, and well into the years when maintenance and repair costs start creeping up. Even more troubling, these borrowers may be stuck if they need to sell their vehicles since they may be “upside down,” owing more than what they can sell their car or truck for.

And why it may not be: Many consumers budget for a car payment, and as long as they aren’t hit with unexpected expenses, they are able to make this payment a priority. In addition, borrowers may be able to refinance their auto loans and lower their monthly payments. Plus cars often get people to work, where they can earn the money they need to pay off debt.

Vehicle loans that are paid on time can help credit scores, and are rarely a problem unless someone has several car loans outstanding at once, or misses a payment.

The Worst Kind of Debt

When it comes down to it, the worst type of debt is … (drumroll please), the one you can’t pay back on time. If that happens, your credit scores will suffer, your balances may grow larger due to fees and interest, and you may find yourself borrowing even more as you try to keep up with your payments.

Hello, Reader!

Thanks for checking out Credit.com. We hope you find the site and the journalism we produce useful. We wanted to take some time to tell you a bit about ourselves.

Our People

The Credit.com editorial team is staffed by a team of editors and reporters, each with many years of financial reporting experience. We’ve worked for places like the New York Times, American Banker, Frontline, TheStreet.com, Business Insider, ABC News, NBC News, CNBC and many others. We also employ a few freelancers and more than 50 contributors (these are typically subject matter experts from the worlds of finance, academia, politics, business and elsewhere).

Our Reporting

We take great pains to ensure that the articles, video and graphics you see on Credit.com are thoroughly reported and fact-checked. Each story is read by two separate editors, and we adhere to the highest editorial standards. We’re not perfect, however, and if you see something that you think is wrong, please email us at editorial team [at] credit [dot] com,

The Credit.com editorial team is committed to providing our readers and viewers with sound, well-reported and understandable information designed to inform and empower. We won’t tell you what to do. We will, however, do our best to explain the consequences of various actions, thereby arming you with the information you need to make decisions that are in your best interests. We also write about things relating to money and finance we think are interesting and want to share.

In addition to appearing on Credit.com, our articles are syndicated to dozens of other news sites. We have more than 100 partners, including MSN, ABC News, CBS News, Yahoo, Marketwatch, Scripps, Money Magazine and many others. This network operates similarly to the Associated Press or Reuters, except we focus almost exclusively on issues relating to personal finance. These are not advertorial or paid placements, rather we provide these articles to our partners in most cases for free. These relationships create more awareness of Credit.com in general and they result in more traffic to us as well.

Our Business Model

Credit.com’s journalism is largely supported by an e-commerce business model. Rather than rely on revenue from display ad impressions, Credit.com maintains a financial marketplace separate from its editorial pages. When someone navigates to those pages, and applies for a credit card, for example, Credit.com will get paid what is essentially a finder’s fee if that person ends up getting the card. That doesn’t mean, however, that our editorial decisions are informed by the products available in our marketplace. The editorial team chooses what to write about and how to write about it independently of the decisions and priorities of the business side of the company. In fact, we maintain a strict and important firewall between the editorial and business departments. Our mission as journalists is to serve the reader, not the advertiser. In that sense, we are no different from any other news organization that is supported by ad revenue.

Visitors to Credit.com are also able to register for a free Credit.com account, which gives them access to a tool called The Credit Report Card. This tool provides users with two free credit scores and a breakdown of the information in their Experian credit report, updated twice monthly. Again, this tool is entirely free, and we mention that frequently in our articles, because we think that it’s a good thing for users to have access to data like this. Separate from its educational value, there is also a business angle to the Credit Report Card. Registered users can be matched with products and services for which they are most likely to qualify. In other words, if you register and you find that your credit is less than stellar, Credit.com won’t recommend a high-end platinum credit card that requires an excellent credit score You’d likely get rejected, and that’s no good for you or Credit.com. You’d be no closer to getting a product you need, there’d be a wasted inquiry on your credit report, and Credit.com wouldn’t get paid. These are essentially what are commonly referred to as "targeted ads" in the world of the Internet. Despite all of this, however, even if you never apply for any product, the Credit Report Card will remain free, and none of this will impact how the editorial team reports on credit and credit scores.

Your Stories

Lastly, much of what we do is informed by our own experiences as well as the experiences of our readers. We want to tell your stories if you’re interested in sharing them. Please email us at story ideas [at] credit [dot] com with ideas or visit us on Facebook or Twitter.
